[0024] The EOD surfactant production equipment in this embodiment is an improvement and optimization of the original EOD device based on the current market demand for surfactant products. This enables it to produce surfactant products, so as to adapt to market changes and increase economic benefits.

[0025] Reference Figure 1 The EOD surfactant production equipment in this embodiment includes a pretreatment tank 1, a treatment tank 2, a posttreatment tank 3, and an intermediate tank 4.

[0026] The inlet end of the pretreatment vessel 1 is connected to a potassium hydroxide pipeline 11, a feeding pipeline 12, and a temporary feeding pipeline 13. In this embodiment, the inlet end of the pretreatment vessel 1 refers to an opening or connector provided in the pretreatment vessel 1 to communicate with the potassium hydroxide pipeline 11, the feeding pipeline 12, and the temporary feeding pipeline 13. Specifically, the positions of these openings / connectors can be concentrated near the pretreatment vessel 1 or dispersed, depending on the actual production equipment, and no specific restrictions are imposed here.

[0027] Potassium hydroxide is added to the pretreatment vessel 1 via potassium hydroxide pipeline 11. Multiple feed branches 121 are connected to the feed pipeline 12, through which raw materials required for producing surfactant products are added to the pretreatment vessel 1. The feeding of the pretreatment vessel 1 by connecting multiple feed branches 121 to the feed pipeline 12 allows for flexible adjustment of the number of feed branches 121 according to the type of product being produced, and facilitates switching of the feed within each feed branch 121, thus enabling adjustments to the products prepared by the EOD production equipment. One feed branch 121 carries 2-PH alcohol, enabling the equipment in this embodiment to produce surfactant products such as IP and IPL. Furthermore, a temporary feed pipeline 13 is designed. This temporary feed pipeline 13 allows for the addition of corresponding raw materials to the pretreatment vessel 1 based on the type of surfactant product to be prepared, thereby expanding the range of surfactant products that the equipment in this embodiment can produce, improving its adaptability to various surfactant products on the market, and ultimately enhancing economic benefits.

[0028] The outlet end of the pretreatment vessel 1 is connected to the discharge pipeline 16, through which the intermediate products that have undergone pretreatment such as catalysis, heating and dehydration in the pretreatment vessel 1 are discharged.

[0029] Processing vessel 2, the inlet end of which is connected to the discharge pipeline 16, that is, the intermediate product obtained by pretreatment in the pretreatment vessel 1 is discharged through the discharge pipeline 16 and enters the processing vessel 2 for reaction.

[0030] The inlet of the post-processing vessel 3 is connected to the outlet of the processing vessel 2 via the feed pipeline 31. That is, the product reacted in the processing vessel 2 enters the post-processing vessel 3 via the feed pipeline 31 for further processing.

[0031] The inlet of the post-processing vessel 3 is also connected to a neutralizing agent pipeline 32. The neutralizing agent is added to the post-processing vessel 3 through the neutralizing agent pipeline 32 to neutralize the product. The outlet of the post-processing vessel 3 is connected to a post-discharge pipeline 38, which is connected to a storage tank pipeline 381. That is, the surfactant product processed in the post-processing vessel 3 is discharged through the post-discharge pipeline 38 to the storage tank pipeline 381, and then enters the storage tank for storage through the storage tank pipeline 381.

[0032] The exhaust end of the post-treatment vessel 3 is connected to a post-exhaust gas scrubbing pipeline 35, a post-vacuum pipeline, and a nitrogen pipeline 37. The post-vacuum pipeline includes a parallel original vacuum pipeline 361 and a new vacuum pipeline 362, with a blind flange 363 installed on the original vacuum pipeline 361. The exhaust gas generated during the treatment in the post-treatment vessel 3 is discharged through the post-exhaust gas scrubbing pipeline 35 to the exhaust gas scrubbing device for treatment before being discharged, thus preventing direct environmental pollution. Additionally, a nitrogen pipeline 37 is designed to purge residual exhaust gas from the pipeline, preventing corrosion and damage to the pipeline caused by residual exhaust gas. Furthermore, the original vacuum line 361 and the new vacuum line 362 are designed to be connected in parallel in the post-vacuum line design. The new vacuum line 362 is used to perform stripping treatment on the produced surface surfactants. A blind flange 363 prevents the surface surfactants from entering the original vacuum line 361, avoiding cross-contamination caused by the original vacuum line 361 sharing the vacuum system with other products, thus ensuring the quality of the prepared surface surfactants. The original vacuum line 361 is retained to allow the equipment to switch to producing other products, increasing the equipment's ability to produce a wider variety of products and improving economic efficiency.

[0033] Intermediate tank 4 has an inlet end connected to an intermediate tank feed pipe 41, which is connected to a downstream discharge pipe 38. Thus, the surfactants discharged from the post-processing vessel 3 can be discharged into the storage tank via the downstream discharge pipe 38 and then into the intermediate tank feed pipe 41, and then into the intermediate tank 4. The outlet end of the intermediate tank 4 is connected to a packaging pipe 42, so that the surfactants in the intermediate tank 4 can be supplied to the filling area via the packaging pipe 42 to achieve on-site packaging of the surfactants and meet different production needs.

[0034] Reference Figure 1 A temporary feeding pipeline 13 is connected to a temporary feeding pump 131. The outlet of the temporary feeding pump 131 is connected to the temporary feeding pipeline 13 via an outlet pipeline. Furthermore, the outlet pipeline is also connected to a bypass pipeline 132, which is connected in parallel with the temporary feeding pipeline 13. Thus, the temporary feeding pump 131 drives the required raw materials into the pretreatment vessel 1 via the temporary feeding pipeline 13. Moreover, the raw materials driven by the temporary feeding pump 131 can also be supplied to other production equipment via the bypass pipeline 132, allowing two pieces of equipment to share a single temporary feeding pump 131, thereby reducing production costs.

[0035] The exhaust end of the pretreatment vessel 1 is connected to the tail gas scrubbing pipeline 14 and the vacuum pipeline 15. The tail gas generated in the pretreatment vessel 1 can be discharged to the tail gas treatment device through the tail gas scrubbing pipeline 14, and then discharged after treatment to avoid direct discharge and environmental pollution.

[0036] An automatic valve is installed on the feed branch pipe 121, an automatic valve is also installed on the potassium hydroxide pipeline 11, and valves are installed on the feed pipeline 12 and the temporary feed pipeline 13. Furthermore, refer to... Figure 1 Automatic valves are also designed on the side branch pipeline 132. In this way, by designing valves on each pipeline, the start-up and shutdown of raw material transportation and the amount of transportation in each pipeline can be controlled.

[0037] Refer again Figure 1 The post-treatment vessel 3 is connected to a circulating water inlet pipe 33 on one side and a circulating water outlet pipe 34 on the other side. Circulating water is added to the post-treatment vessel 3 through the circulating water inlet pipe 33, and after cooling it, it is discharged from the circulating water outlet pipe 34 to maintain the post-treatment vessel 3 within the required temperature range, thereby improving the quality of the produced surfactant products.

[0038] A blind flange 363 is located at the inlet of the original vacuum line 361. A sealing element is provided on the outer periphery of the blind flange 363 to improve the blocking effect on the surface surfactant and prevent it from entering the original vacuum line 361. The downstream discharge line 38 and the storage tank line 381 are equipped with automatic valves to control the discharge and discharge volume of the surface surfactant.

[0039] A stirring element is installed in each of the pretreatment vessel 1, the treatment vessel 2, and the posttreatment vessel 3. This stirring element is connected to a drive motor, which is located outside each of the three vessels. The drive motor rotates the stirring element to agitate the materials within the three vessels, thereby improving the reaction processing efficiency.

[0040] In this embodiment, a control module (not shown in the figure) is also included. This control module is connected to the pretreatment vessel 1, the processing vessel 2, the post-processing vessel 3, and the intermediate tank 4. For example, the control module adopts a DCS control system, which is connected to the pretreatment vessel 1, the processing vessel 2, the post-processing vessel 3, and the intermediate tank 4. Specifically, it can be connected to devices (such as thermometers) installed on them, valves installed on each pipeline, etc., to monitor the reaction process inside.

[0041] The EOD surfactant production equipment in this embodiment, through the combined arrangement of pretreatment tank 1, treatment tank 2, post-treatment tank 3 and intermediate tank 4, has the capacity to produce surfactants and can meet the production needs of various surfactants. In addition, it can ensure the quality of the produced surfactants. Furthermore, it can realize the storage of surfactants in storage tanks and on-site packaging, resulting in good economic benefits.

[0042] Where the embodiments do not contradict each other, at least some of the technical solutions in each embodiment can be recombine to form the essential technical solution of this utility model. Of course, the embodiments can also reference or include each other. Furthermore, it should be noted that adaptive adjustments and modifications made by those skilled in the art when recombinating the technical means described in the embodiments will also fall within the protection scope of this utility model.

[0043] The technical principles of this utility model have been described above in conjunction with specific embodiments. However, it should be noted that these descriptions are merely for explaining the principles of this utility model and should not be construed as limiting the scope of protection of this utility model in any way. Based on this explanation, other specific embodiments or equivalent substitutions of this utility model that can be conceived by those skilled in the art without creative effort will all fall within the scope of protection of this utility model.
